WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
1. Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
4. Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.

Waste heat steam boiler Benefits of waste heat steam boiler. 1.Increase in efficiency and environmental responsibility through use of waste heat sources 2.High efficiency through efficient tubular heat exchanger and good thermal insulation 3.Additional efficiency gain 4.Simple commissioning due to pre-parameterised boiler control 5.Easy wiring
Apr 17, 2020· A waste heat boiler of the water-tube design is able to cope with much higher pressures of steam than a fire-tube boiler, but it is more difficult to construct and install. Inside this type of boiler, there are narrower tubes than inside a fire-tube boiler, and the tubes contain water instead of hot gases.

a boiler without its own firebox, which uses the heat of waste gases from industrial or power equipment. The temperature of gases entering a waste-heat boiler is 350°-400°C (in the case of a boiler installed behind an internal-combustion engine) to 900°−1500°C (if it is installed behind a reverberatory or refining furnace or a cement kiln).
A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency. The WHRU is a tool involved in cogeneration.Waste heat may be extracted from sources such as hot flue gases from a diesel generator, steam from cooling towers, or even waste water from
The Incline HRSG reclaims waste heat from a Centaur 40 gas turbine and supplies 19,200 PPH / 135 PSIG steam to the prison for heating and process users. The boiler and auxiliary equipment were delivered and were successfully started up.
Mar 06, 2018· TYPE OF HEAT LOSS IN BOILER AND THEIR PREVENTION . in this article we discussed about the Type of heat loss in boiler and their prevention. in power sector each boiler is not 100% efficient it has some losses so that the boiler efficiency remains up-to 75-80% in generally operating conditions and remaining 20-25 % are considered into loss . these losses reducing the …
Waste Exhaust Heat Boilers. Approximately 25% of the usable energy of the fuel gas is released in the exhaust of the gas engine. This can be captured for cogeneration in a combined heat and power plant. This heat exits the engine at ~450 o C as ‘high grade heat’, contrasting to ‘low-grade heat’ available from the generator cooling circuits. This high temperature and flow makes it well
